Fresh hacks every day
If you’ve got a BeagleBone and an FPGA board you should give this Bitcoin mining rig a try. The hardware uses brute-force to solve hashes, looking for the rare sets that can be used as digital currency. This particular example is designed for the LOGi-bone which is an FPGA shield for the BeagleBone. But we don’t see anything that … Read the rest
When the developer of the µTorrent torrent client and the ScummVM LucasArts adventure game interpreter gets bored, something cool is bound to happen. Luckily for us, [Ludde] was a bit listless over Christmas, and with more time than energy to burn, implemented a Nintendo Entertainment System on an FPGA dev board.
The NES was powered by a Ricoh 2A03 CPU, … Read the rest
Out of the depths of a junk drawer, [Alex]‘s friend pulled out an old monochrome LCD display. This is an older low-resolution display from ancient electronics that unfortunately doesn’t have its own controller chip. No worries, though, because with the help of an FPGA [Alex] figured out how to drive this display.
On the back of this display are … Read the rest
Free-formed VFD clock
[James] doesn’t need a circuit board or even some protoboard to get the job done. He free-formed all the circuits for his VFD clock. Right now this is the only project hosted on his blog so click around to see how he got to this point.
DIY LED traffic light
Here’s a scratch-build traffic light which … Read the rest
A few years ago the folks at Astro Designs put together a board that took off-the-shelf CCD sensors from point and shoot cameras and turned them into respectable astrophotography sensors. Since then, the world has seen an explosion of Raspberry Pis, Arduinos, and other microcontroller platforms, making this the perfect time for a hardware revision.
Their PiXi-200, like their … Read the rest
[Chris] is an IT guy for a medical clinic up in Alaska, and until very recently the systems he monitored, fixed, and beat with a wrench included over 100 Pano Logic “Zero Client” thin clients. Pano Logic just went out of business and all support for these little boxes have been cut off, leaving [Chris] with a hundred or so … Read the rest
[Andrew Holme] wrote in to tell us about some work he’s done to improve his scratch-built GPS receiver. He figured out a way to use the same hardware but double the number of satellites it can track to a total of eight. When we looked at the original hardware about a year ago it was limited to monitoring just … Read the rest
